 Note that this release includes a change in Synapse to use Redis as a cache ─ as well as a pub/sub mechanism ─ if Redis support is enabled. No action is needed by server administrators, and we do not expect resource usage of the Redis instance to change dramatically.
 
+This release also changes the callback URI for OpenID Connect (OIDC) identity
+providers. If your server is configured to use single sign-on via an
+OIDC/OAuth2 IdP, you may need to make configuration changes. Please review
+[UPGRADE.rst](UPGRADE.rst) for more details on these changes.

+Changes to callback URI for OAuth2 / OpenID Connect
+---------------------------------------------------
+
+This version changes the URI used for callbacks from OAuth2 identity providers. If
+your server is configured for single sign-on via an OpenID Connect or OAuth2 identity
+provider, you will need to add ``[synapse public baseurl]/_synapse/client/oidc/callback``
+to the list of permitted "redirect URIs" at the identity provider.
+
+See `docs/openid.md <docs/openid.md>`_ for more information on setting up OpenID
+Connect.
